Wastewater Treatment Technology Custom Biologicals Custom Biologicals use bioaugmentation, sometimes called wastewater bioremediation, to treat a wide variety of wastewater problems. Bioaugmentation is a wastewater treatment technology that uses the addition of specifically selected microorganisms, or microbes, to treat wastewater. The use of bioaugmentation at wastewater plants is designed to treat a variety of wastewater problems such as: Wastewater Odor including hydrogen sulfide (H2S) odor FOG (fats, oils, and grease) problems High COD, BOD, TSS, or sludge Petrochemicals and hydrocarbons Fiber – pulp and paper wastewater Custom Biologicals main wastewater treatment product is F-TREAT. F-TREAT contains billions of specifically selected, wastewater treatment bacteria. These bacteria have been selected for their safety and their enhanced ability to metabolize the organic compounds typically found in wastewater streams. Additionally, Custom Biologicals has the ability to “customize” F-TREAT for a particular application. If you have a wastewater problem that others have tried and failed, Call Custom. We can customize a wastewater solution for you. F-TREAT is a wastewater treatment technology used in a wide variety of situations including: Industrial wastewater Food Processing wastewater Pulp and Paper Wastewater Municipal Sewage systems Lift Stations Petrochemical Refineries Custom Biologicals manufactures and distributes the following wastewater treatment products. F-TREAT – wastewater treatment bacteria. F-TREAT is a liquid concentrate...

Hydrogen Sulfide (H2S) and Bacteria It is well known that wastewater and sewage has a very high potential to produce nasty odors such as hydrogen sulfide (H2S, ammonia, indoles, skatoles and mercaptans. Of these hydrogen sulfide (H2S) is arguably the most import mainly due to toxicity, its ability to corrode materials, and it is the major source of odor problems at wastewater treatment facilities, manholes, and lift stations. The conditions leading to hydrogen sulfide formation favor the production of other odiferous organic compounds. So solving an H2S odor problem can often solve other wastewater odor problems as well. Sources of Hydrogen Sulfide in Wastewater Sulfur is present in both human and livestock solid wastes and sulfates are found in most water supplies. Almost all wastewater has a sufficient amount of sulfur for both anaerobic bacteria and facultative bacteria to produce hydrogen sulfide. Generally, these bacteria produce H2S as a byproduct of their metabolism. By a process called anaerobic respiration, anaerobic bacteria oxidize organic compounds while reducing sulfate (SO4) to hydrogen sulfide (H2S). Interestingly, sulfate reducing bacteria are considered one of the oldest forms of life on earth. They are some 3.5 billion years old. Hydrogen Sulfide Production Rate The rate that anaerobic bacteria produce...

Why Aeration Alone Won’t Make My Lagoon Odor Go Way? Here’s the situation. You have just purchased, or recommended, the company purchase, an expensive aeration system to take care of your lagoon odor problems. After all, the salesman said it would work. He explained that aerobic bacteria don’t create those nasty H2S odors, anaerobic bacteria do. So by simply adding aeration, you’ll change the environment in the lagoon. And Presto – Rotten Egg Odor Gone. No more neighbors complaining about lagoon odor. So you spend the money, install the aeration system and turn it on. Unfortunately, the odor problem doesn’t go away. IT GETS WORSE! An Overwhelming stench of hydrogen sulfide fills the air and your nostrils. The installer says not to worry, it will get better over time. So what just happened? Why didn’t the lagoon odor go away with aeration? First, we’ll need to talk about the microenvironmental situation in the lagoon. In a typical wastewater lagoon, the wastewater stratifies. In other words, some of the water floats and some sinks. Because of this, only the top layer of the wastewater lagoon receives oxygen. As a consequence, obligate anaerobes ( bacteria that cannot survive in the presence of oxygen) proliferate in the lagoon. Obligate anaerobes (bacteria that...

Using Fizzytabs to Reduce Lift Station Odors Lift station odors are one of the most common complaints and one of the most common lift station problems. The lift station tends to accumulate fats, oils and grease in the lift station and on the sides of the lift station. Now, Custom Biologicals has come up with a cost effective, environmentally safe, solution to the lift station odors problem – Shock Treatment Fizzytabs. Shock treatment fizzytabs are effective in treating lift station odors, particularly when the odors are cause by grease on the sides of the sewage lift station. Shock treatment fizzytabs are a unique, effervescent tablet that contain billions of beneficial bacteria. These bacteria have been specifically selected because of their enhanced ability to metabolize the fats, oils, and grease (FOG) that accumulate in sewage lift stations. Most lift station odors are caused by the decay of organic materials, specifically FOGs. This decay is the result of incomplete digestion of the organic material by the indigenous bacteria, both aerobic bacteria and anaerobic bacteria. In particular, these indigenous bacteria produce hydrogen sulfide (rotten egg smell). The bacteria in Shock Treatment Bacteria do not produce hydrogen sulfide. In fact, they digest the fats, oils, grease, and other organic material that cause lift...
